“SE1” warning occurs when the keypad does not transmit the COPY command
to the drive and does not transmit any data to the drive again in 10 sec. at the
time you copy the parameters to the drive.
SE1: The causes of error are mostly communication problems between the
keypad and control board. Potential causes include communication signal
interference and the unacceptable communication command to the Slave.
It is recommended to rule out communication quality factors first.
Check if the error occurs randomly, or only occurs when copying certain
parameters (the error displays on the upper right corner of the copy page). If you
cannot clear the error, please contact Delta.
